Cannot unmount firewire drive due to compressord

I was working off a Firewire 400 drive doing work with Motion and Compressor. I am done, quit all my apps, try to eject the drive. I get a "device is busy" error and it will not eject.
There are no running applications, and force-quitting the Finder has no effect on this.
I ran "losf" in Terminal and got one open file:
compresso 1643 stevel 40r VREG 14,8 0 20785 /Volumes/PSYDUCK/Armor Animation/images/ies/LPFCPull.mov/..namedfork/rsrc
I notice that a "compressord" process in running, although Compressor has been quit.
I kill compressord with sudo in Terminal, and now I can unmount the drive.
Is this normal behavior? It's annoying and took me 1/2 hour to track down. I don't know why this file was kept open.
Any ideas?

Mmmmhmmm. Well when your computer is running through the installation preparation screens, there should be one where it will ask you where the location is you want iTunes to be loaded into. Change it to drive C. That SHOULD do it.
To be honest...I wish I had a Mac. Seems like they are much more reliable.

Cannot eject FireWire drives

Hi,
Whenever I mount a firewire drive, I cannot eject it again - I always get a -47 error, saying the drive is busy. I have TimeMachine turned OFF, so that shouldn't be causing the problem. Also, I never had any problems with this under Tiger.
Any ideas? I have tried all possible ways of unmounting the drive, but nothing works (except pulling the plug obviously.....)

Cannot unmount External drive for backup....help

I am trying to use a new My Passport external drive to backup. I installed the mac os info however it says I must "erase" contents to use. When I hit erase it says the drive "couldn't unmount". Also tried to backup to the drive and it said "disk is not in Mac Os Extended (journaled) format. Any ideas, I am not real familiar with this process.

Hi KJM4,
Thanks for using Apple Support Communities. Based on what you stated, it sounds like you need to format the HD. I would recommend that you read this article, it may be able to help the issue.
Final Cut Pro X, Motion 5, Compressor 4: Format drives as Mac OS Extended - Apple Support
Formatting a disk using the Mac OS Extended (Journaled) format
Important: If you have any files you want to save, be sure to back them up to another drive before you erase the drive they are on. Reformatting a drive will permanently erase all of the data on it.
From the Finder, click the Go menu and choose Utilities.
Open Disk Utility.
Select the disk or partition and click Erase.
Choose a format from the Format pop-up menu. Choose Mac OS Extended (Journaled).
Type a name for the disk.
If you want to prevent the erased files from being recovered, click Security Options, select the option you want, and click OK.
Click Erase.
Cheers,
Mario

Cannot unmount hard drive

I have no idea what is happening with it, but everytime I try to eject my HD I cant and I also cant try to repair it in disk utility because it cant be unmounted! Has anyone got any ideas? I have tried to restart the computer

Is this an external hard drive? You can't eject a drive your running from (i.e. the internal)
To use Disk Utility to repair your internal drive startup cmd-r to your recovery volume and choose Disk Utility.

Manual unmount Firewire hard drives before shutdown

I'm having shutdown problems again possibly due to my new firewire hard drive, the firewire driver supplied by OS X, or some combination thereof.
The issue is if I don't manually unmount my Firewire hard drive, the MacBook Pro does not ever properly shutdown and just spends its time doing the "spinning sun ray". If I manually unmount the firewire hard drives (by dragging to trash, for example) then there is no shutdown problem. Why should this be a problem at all? I don't understand. Why can't the shutdown command also unmount Firewire hard drives consistently?
My set up:
MacBook Pro <--> LaCie 120Gb firewire <--> Maxtor OneTouch 4 Plus 500GB
I also saw this article:
http://www.fcpworld.com/fcpworld/articles/E14514A0-F957-48E4-835A-81CE505C03D5.h tml
Any times on how to solve this problem so that I can go to the shutdown command without first having to manually unmount the Firewire hard drives? Thanks!

Thanks for reporting back, the idea was just a theory that I had never tried before. I do know that Macs will have difficulty shutting down if the state of a network is changed during to shutdown, say pulling the ethernet cable. Firewire has been implemented as a network port (actually a while ago).
Yeah, I've known Firewire was implemented as a network port a long time ago. The strange thing is that I'm not using the Firewire port as a network device AND it has also been deactivated. It was deleting the port that seemed to have helped it.

Boot from external Firewire Drive-cannot repair or optimize internal drive.

Hi all
Connected my new 300 GB Seagate External Firewire Hard Drive today.
Installed Tiger from DVD. Updated to 10.4.3.
Installed Tech Tool Pro 4. Updated to 4.1.1.
Booted from External Firewire Drive.
Disk Utility cannot Verify or Repair internal drive. Does not say or do anything.
Tech Tool Pro cannot repair volume or optimize. Says, "Cannot Unmount Volume."
Is there a fix for this?
Thank you for the help!

Hi
I did name the new external completely different from the internal.
After booting from the external Firewire Hard Drive, I tried running Disk Utility and Tech Tool Pro from both drives. No matter which drive I run the Utilities from the same things happen every time...
Nothing happens when trying to use Disk Utility to Verify Volume on internal eMac Drive.
Tech Tool Pro says, "Cannot unmount volume" when trying to check Volume or Optimize internal drive.

Cannot Boot from OSX on external firewire drive

I recently bought a seagate hardrive and installed it in an external firewire casing. I partitioned it into two partitions, and installed osx 10.4.10 on one of the partitions, the same as is running on my Ti Book.
I tried selecting the os on the firewire drive as the startup disk, but when i restart, after the grey screen i get the flashing question mark icon, until the mac recognises only the default osx on the internal drive and boots with that instead.
That not working, i created a clone of my startup disk using DejaVu in my system preferences and saved it on the other, empty partition on the external drive and tried booting from that.
On restarting, i get the grey screen once again as the backlight fires up, and nothing more. the screen remains grey without any further ado until i hold the power button and force it to turn off. then as i start it up again, up comes the flashing question mark icon followed by a boot from the internal drive.
Any Solutions on this?
Many Thanks, Neptune.

Hi Dale,
Whoops- everythings not as smooth as i thought it was!
since i restored my internal drive, a lot of things have been really messed up, starting with, for example, iTunes reverting to version 4 instead of 7. that wasnt a problem, i still had the 7 installer, and soon had my whole music library back again. but the computer appears to have a problem with the handling of graphics. the finder wont create previews of even simple jpeg images, nor will it for video. quicktime wont open any video file, i get some random error message which i cant remember stating it could not open the file. and if i view my finder window in grid icon view, the usual blue mac os desktop image that i keep as a background in the finder window isnt there, instead its pitch black. same goes for the slideshow feature in the application graphic converter, i can start a slideshow and it will scroll through the images, but every image will instead be completely black. there are no scroll bars in itunes. i can scroll down randomly by clicking where the scroll bar should be, but there is nothing visual there at all, no scroll bar, no arrows. when i connect my ipod, the main ipod window of itunes wont display any graphics either, be it the picture of the ipod or the capacity bar indicating usage of the drive for music, videos, data, etc. instead, fine print says something similar to 'cannot display image, quicktime and lzw tiff decompression plugin (?) required' I cant remember word for word what it says, dont quote me on that.
the computer also came to a dead freeze twice in ten minutes, i had to hold the power button down to get it to shut off.
im sure there are other issues too which i havent yet noticed, but even these, i havent the faintest clue what could be causing them!
do you?

Please Help! - Cannot Access Or See External USB/Firewire Drive

Can anyone help or advise me as I’m really at a loss as how to fix a problem I have with my external hard drive and OX 10.4.6.
I had just completed a fresh install of OS X on my PowerPC iMac G5 using the “Erase & Install” feature.
Everything had gone extremely well, all my applications and settings had been re-set as I normally have them (I made backups) and was able to access my external hard disk, which is a Maxtor OneTouch USB/FireWire 250 GB model.
I then setup a second account for my brother, which I setup as a “Standard” account.
When I then went to access some of the files on my external disk and tried to copy them over to my Desktop, it refused me permission and said that I had to ask the permission of the “Owner’ which it said was Steve (my Brother) which was strange because as I said his account was only setup as a standard account whereas I had an administrator account (and am the main user of the computer).
I went into the Steve's account and looked at the Permissions information using the “Get Info” dialogue box. This showed that the owner was indeed Steve, so I changed it to my Name (Andrew) went back to my account, and found could no longer see the external disk at all.
Returning to Steve’s account I checked the permissions again, and asked it to ignore permissions.
But now I cannot see or access the disk at all in either account, it just does not show up on the desktop or in the Finder Sidebar.
The strange thing is I can see it in “Disk Utility” but when I ask it to either verify or Repair the Disk permissions, it reports that they are all or OK and “no repairs were necessary”.
I have tried connecting the disk with both types of connection - USB2 and the Firewire drive, and the results are exactly the same, the drive is not visible on the Desktop or the Finder Sidebar, but is visible to Disk Utility.
The disk is formatted as a ‘Mac OS Extended (Journaled) drive
Can anyone please tell me how I can get my external disk to show on my computer again, as ALL my backup documents and programs are on the disk, and most of the data cannot be replaced.
Would doing a complete fresh install of the OS X operating system fix this as a last resort?
I hope someone can advise, as I really am desperate.
Thanks

Yes, I didn't think it was very good either!
You are correct in I should have said "Repair Disk" - Verify Permissions is not available on the maxtor drive ( it is dimmed) in Repair Disk.
Until now, the drive has worked perfectly, and I did not install any of Maxtors software when I originally connected the drive to this system, I just formatted it as a Mac Extended and it worked great. It was only after the fresh Erase & Install - even then it worked fine. It was only when I created a new account that the problem started.
What I have done is get hold of a demo version of a program called "Mac Drive 6" which allows you to read any Mac formatted disk or drive on a Windows system, - fortunately i still have my Windows XP Pro system which I have also connected to my home network.
So for the next four days (the length of the demo) I can access all of my files on the disk and copy them to my Windows system.
This is really great because I have all my data and images back which were my biggest concern.
I thought I might get another drive anyhow, and when I have everything backed up on a new drive and on the Windows system, I can then reformat the Maxtor drive and start afresh with it.
Thanks for all your help anyhow.

HELP! Firewire Drives Unmounting by themselves.

I have a small workgroup with a G4/800 server with two FireWire drives connected. One of the drives contains ALL of the organizations files and is shared over the network using the SharePoints software. The other Firewire drive is just a backup drive which is used by Retrospect. What is happening is the users will frequently find the firewire shares mounted over the network on their machines will disconnect and users will receive an alert telling them that the network volume is no longer available or something. When we go to the server we find the Firewire drives are no longer mounted on the desktop. Otherwise, the machine is running normally. Trying to remount the drives usually does not work and I have found that the only surefire way to get them back is to turn the drives off, restart the machine, then turn the drives on. After that, they will mount fine and once again become available to the clients' machines.
I am at a loss as to what would be causing these volumes to unmount or eject themselves. Can anyone help me to troubleshoot this?

External hard drive spontaneously unmounted? Try these tips:
NEW FIRMWARE: Try updating your external hard drive's firmware, which is available from your drive manufacturers Web site--or just use VersionTracker's (www.versiontracker.com) search function to find it. Be sure to back up your data before applying the update, and carefully follow the manufacturers instructions.
OUT OF iSIGHT: If you're using an iSight camera while you're using a FireWire drive, the camera may be interfering with the drive's ability to stay mounted. Try temporarily disconnecting your iSight and moving it to a separate FireWire port. If you have multiple FireWire devices, try using a FireWire hub.
POWER PROBLEM: A faulty power adapter could be causing your drive to unmount. Your drive may not be getting enough juice to stay on, causing the drive to turn off and thereby unmounting it from your Mac. Alternately, the power adapter may not be providing a steady amount of power, causing your drive to turn on and off. Try replacing the adapter. If you can't get a replacement adapter from the hard drive manufacturer, try your local electronics store. Just make sure the adapter you choose has the same connector and input/output voltage. you can find the input/output voltage on the adapter itself.

FireWire drive keeps unmounting when nobody's logged in

I have a Core Solo Mini I am using as a server for various purposes (shared iTunes and web server, with another partition reserved for Time Machine once Leopard comes out) as well as for normal desktop use for my wife and kids. The server partitions are all on an external 400 GB FireWire drive, since the mini's internal drive is so small.
[FWIW, I used to use a Cube in this fashion, but came up against its 120 GB limit for internal drive]
Anyways, even though I have it set to share the FireWire partitions via AFP, and even though I've pointed Apache over to directories on the FireWire drive as the root directories for various virtual hosts, the machine still has a habit of unmounting the FireWire drive if nobody's logged in and I'm not actively using the net-mounted drive on another machine (eg, if I'm not playing iTunes off of it).
When this happens, trying to browse its drives from another machine only shows the internal partitions, not the FireWire drive, and Apache barfs up errors like "document not found for /".
This kind of s*cks. Is there any way I can get OS X to never unmount the FireWire drive?
To answer the obvious question: yes, the mini is set to never sleep.
Thanks in advance.

I had a similar unmounting issue with one of my internal hard disks that I was using for nightly backups. I discovered that when no one was logged in the backup would fail. I have to look up the required fix to keep the disk mounted, someone here gave me the method for changing that default behavior with a simple terminal command. Don't have it handy with me right now, but I think this should be fixable by the same method for your FW drive. I'll post it later, if someone else hasn't before me.

Cannot create vault on FireWire drive

I have a FireWire drive with two partitions. One partition is a mirror running under SoftRAID. The other is an ordinary Mac partition. Aperture will not create a vault on the Mac partition, generating an error message saying that Aperture cannot create a vault on a networked drive. It says that it will only work on local drives or those connected by FireWire or USB. But this drive is connected by FireWire. Is this some sort of strange incompatibility with drives partitioned by SoftRAID?

I have two valuts, both are on external FireWire drives (as is my library). Neither of these is attached to any kind of RAID array. My guess is that SoftRAID is causing your problem.
Have you tried "unRAIDing" the drive to see if it will create then? or attaching a different disk and trying that?

Firewire drives random unmount

I have 2 WD My Book external drives attached via Firewire to my 27" iMac, one is used for Time Machine backups the other is additional system storage
I had this config running under Snow Leopard on this system and my earlier 24" iMac with no issues.
Since upgrading the 27" iMac to Lion I am experiencing random unmounts of both Firewire drives with the result that the Time Machine backups are failing and I have to physiclly reset the external drives to get them to sucessfully mount again.
Both WD drives have the latest firmware and OS X is up to date - any thoughts how to resolve this problem and keep the Firewire drives mounted at all times ??

No, never solved the problem, I still get the Firewire drives randomly unmounting and I have to power then down to get them to remount - this never happened with Snow Leopard ( or prior OS versions on my previous 24" iMac ), only started after the Lion upgrade.
